Solve the system of equations by graphing.

Answers

Answer 1

Answer:

x = -2, y = -4 (-2,-4)

Step-by-step explanation:

1. Substitute "y = 2x+ in for y in "x + y = -6"

x + 2x = -6

2. Combine like terms:

3x = -6

3. Isolate x:

3x/3 = -6/3

x = -2

4. Substitute the new x-value in one of the equations:

y = 2(-2)

y = -4

The graph should look like the picture attached.

hope this helps :)

Answer: Sandy, do not overlap

Step-by-step explanation:
To find the volume of a rectangle, you use the formula

volume = length x width x height

the height of both rectangles is 8

The height of the top rectangle is 4

So you take the 8-4 to get the height of the bottom rectangle which is 4.

By finding that it shows that Sandy’s volume equation is correct, and the shape shows no signs of overlap.

Elena wants to create a triangle shaped garden that has an area of 36 square feet Name all the different dimensions her triangle can be in feet. Pls help

Answers

Answer:

Base = 18 Height = 4 (this is an example)

Step-by-step explanation:

Given that the triangle has an area of 36 square feet, and that the triangle area formula is A=1/2bh (b being the base, and h being the height), we can fill in the formula to get the dimensions.

To find the given numbers, we need to find what numbers are divisible to by 2 to get 36. For instance using the formula A=1/2bh, we can plug in the factors that make up 72 (if you divided it by two you will get 36). Example of this is 18x4, so we can plug it into the equation to prove it through factor trees (feel free to reach out if you have a question about those). Plugging 18 and 4 will give 18x4 divided by 2 = 36.

Stephanie is helping her band collect money to fund a field trip.
The band decided to sell boxes of chocolate bars. Each bar sells
for $1.50 and each box contains 20 bars. Below is a partial table
of monies collected for different numbers of boxes sold.
Boxes Sold (b) Money Collected (m)
1 $30
2 $60
3 $90
4 $120
5 $150
6 $180
7 $210
8 $240

1.) Complete the table above for all values of m.

2.) Which is the independent variable?

3.) Which is the dependent variable?

4.) Write an equation for the amount of money, m, that will be
collected if b boxes of chocolate bars are sold.

5.) Graph the equation using the ordered pairs from the table
above.
(Don’t forget to label your axes and increments!)

6.) How much money will be collected if 100 boxes of chocolate
bars are sold?

7.) The band collected $1530 from chocolate bar sales. How
many boxes did they sell?

Answers

Answer:

Step-by-step explanation:

for the table for every box just add 30 more dollars 1.5x20=30

The independent variable is I believe the box of candy bars

And the dependent is the money collected

m=30b since a 1 box is 30 dollars

m=30(100)

m=3000 they will make 3,000 dollars with 100 boxes

1530=30b

/30. /30

51=b

51 boxes of chocolate bars when they make $1530 dollars
